Get a jump start on your next vacuum tube project with the AWA High Voltage Power Supply Printed Circuit Board. This PCB is the foundation for a linear, variable, regulated, power supply that will supply up to 330 VDC @ 500 mA. Click "Show More" for details.
The flexible design accepts AC or DC input, on board or external pass transistors and heat sinks and on board or external potentiometers.
This makes a great bench supply, but with dimensions of only 3.5 x 2.5 inches, it's small enough to embed as a component in your next project.
Applications include:
1. Tube audio amplifiers
2. Tube amateur radios
3. Regulated screen supplies for tube amplifiers
4. Part 15 AM broadcasters
5. Tube phono oscillators
6. Tube VFOs
7. Tube preamps
8. HV bench supply
9. Speaker Field Coil replacement
10. Replace cold cathode voltage regulators
11. Nixie Tube projects
$16.50 shipped free to US addresses. Contact dean@antiquewireless.org for foreign shipping or quantity discounts.
Purchase at antiquewireless.org/homepage/purchase-pcb-items
It's also available on eBay, but you'll pay $2 more for eBay's cut: ebay.us/hInLUB
You are purchasing a bare Printed Circuit Board (PCB) ONLY. This printed circuit board component and the resulting high voltage power supply are intended for experienced persons, and the supply produces potentially dangerous voltages. The schematic and a representative component list will ship with the PCB. No other components are included.
